Incorect signature

[JumboJet5]

Hi

I have a issue with signMessageV2 on iOS version - 17.0 tronLink app version - v4.13.8

When I try to sign message, I got wrong signature

Example:

on app

    tronWeb: 5.1.0-m-1.7
    message: Message
    method: signMessageV2
    sign: 0x57df6449d0d8eca7a87101022a37dccffd226f4d4588ffc33aae6ff9494a857457df6449d0d8eca7a87101022a37dccffd226f4d4588ffc33aae6ff9494a85741b

on web

    tronWeb: 5.1.1
    message: Message
    method: signMessageV2
    sign: 0x57df6449d0d8eca7a87101022a37dccffd226f4d4588ffc33aae6ff9494a85745c54789f6b985b55f61039698fb0c8a083c56195b95e76a7ef99df30e527e2851b

both signed by TTYtkC5FmWm8VMan7xvhkwLVApE9MubY8S wallet

same with sign method

As I've tested, the function has no problem. Maybe you used different private key? You can use tronweb.trx.verifyMessageV2 to get the signer address. Obviously, they are different address.

I'm pretty sure that address was same

Problem relative only for iPhone app

for example:

iPhone app

    tronWeb: 5.3.0-m-1.9-m-1.9
